Programming the outside IP address on a ASA 5505

[Diogi]

We just upgraded our internet service with Spectrum and our outside (Puplic) IP address has changed, how do we change the outside IP address in programming? I see the old outside IP address, when I click on the IP address and click on edit, I do not see the old IP address to change it to the new IP address?

1) Do a "show run interface" on the CLI and locate which interface VLAN has the old outside ip address.

2) configure the following:

interface vlan x

ip address x.x.x.x y.y.y.y 

x.x.x.x is new ip address and y.y.y.y is subnet mask

Be sure to not be connected via the outside interface when you make this change.
